Product analysis
Insomnitol combines herbs, melatonin and other compounds for people seeking a single bedtime blend. Several individual ingredient contributions are costly at the full serving price.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality32
Several herbal markers and the GABA source are identified, but their combined quality remains uncertain. Theanine, 5-HTP and melatonin lack clear form disclosure, making some preparation comparisons harder.
Ingredient Transparency88
All listed ingredient amounts are disclosed, allowing the serving to be checked. Three ingredient forms remain unspecified.
Value For Money29
Valerian, theanine and 5-HTP offer limited value at the full serving cost. GABA is also relatively costly, while value for several other contributions is uncertain.
Customer Satisfaction70
Customer ratings are favorable. The small number of ratings limits how broadly that satisfaction can be interpreted.
Product Focus69
The combination has a clear bedtime orientation, with several ingredients serving related purposes. The number of active ingredients makes it less simple to judge than a single-ingredient choice.
